AMD Zen 2 (Ryzen 3000) - *** NO COMPETITOR HINTING ***

[Yaayuh!]

I see all over the internet this myth that VDDG should be 40-50mv below SOC. This is a Chinese whisper if you ask me.

This is from the likes of the Stilt and 1usmus, but what makes them qualified to say this is correct?

Show me AMD words that say the same and I'll believe you.

The only official AMD words I can find come from the Ryzen master documentation that says VDDG and SOC should be started at 1.1v for ram (IF) overclocking.

Page 34

This bothers me clearly. As the one aspect I hate about overclocking is the unknowns and when certain things get thrown around as fact, when in the end they are just whispers which have became truths.

---

It bothers me because I think the VDDG voltage might be the missing ingredient to getting my ram stable, something I have not been setting as the dram calc claims that 0.950v which is stock was sufficient. (Hence my instability)

---

Anyway I've set both SOC and VDDG to 1.1v and if things are still stable in a good 3 weeks I'll know I'm in the clear.

Try CLDO_VDDP 1000mv I found this helped after Ramad mentioned over at OCN that he felt that it was too low by default and suggest 980-1000mv

CLDO_VDDG should be at least -40mv from SOC voltage. At least that always used to be the case.

But why?

I have a nice stable system.

It seeks to confuse and nigh on decieve consumers.
Whether it's better than Intel's offerings isn't relevant to that specific.

Yup.

The last thing we need right now is another out of stock 12 core.

I can only go off my experiences and the using the dram calc settings (voltages) and I am not stable.

I have been noticing a lot of people on the forums are pushing their VDDG voltage to 1.1v so this is what I'm trying.

And it kinda makes sense really. It's essentially an IF overclock we are doing, so makes sense to need to bump the VDDG voltage.

And the value of 1.1v I am basing off of AMD documentation rather than a third party utility like the dram calc.

The only thing that bugs me is at 1.1v it is red in the bios. Back it down a smidge to 1.075v and it goes yellow.

Maybe in a few weeks if all seems well I'll take it down to 1.075v.

The first thing we need right now is a 12-core with more conservative clocks, so all chiplets can qualify for the SKU.

ABBA has arrived for ASUS Prime Pro X470 in case anyone is interested.

I know your gonna say I’m trolling again but. How can a lower clock speed cheaper 12 core cpu work in the amd lineup?

putting out a more consertive chip lets say 3600 speeds and sell it at 400 pounds that would eat away at the ryzen 3800x sales and price point and will cause the ryzen 3800x price to drop!

amd would be offering you a unlocked 12 core that could proberly match the 3900x with all core overclocking or even get close with twinkering with core clocks across the board

intel are very rigid on there pricing and SKU lineup between there K’s and non -k cpu there cover the price spectrum amd have followed the pricing structure of intel but in turn that does not leave much room for new cheaper sku on the upper tier CPU’s

now what I say could be thrown out of the window if intel force cpu prices down they do indeed bring out a 10/20 i9 proberly close to the 3900x launch price and do indeed bring out a i7 8/16 cpu at close to the 3700x prices.

but it’s down to intel to force prices down and it will how good the new intel cpu is. And if they bring hyperthreading back to i7 this time or will i7 be a pure 10core or a 8/16 and will the i5 will become also. So much is unknown atm and not 1 of us can predict the future.

 

[Woodsta888]

Yeah I wondered this^^^ as a 3800X owner, who gets all the performance as advertised, and some, whilst never drawing more than 60W. If they brought out a 3800, would it sit between the 3700X and the 3800X. There isn't much in them now except the ability for the 3800X to draw more power.

So I can see if a 3900 gave similar perf to the X then I can see why some would be a bit miffed

 

[opethdisciple]

That's why the clock speed is low. Hence my comments about it not being a great choice as a gaming CPU.

These will be pure workstation cpus.

 

[opethdisciple]

We should really have the ability to delete our posts.

 

[marms]

There's not much chance of the 3900 getting close to the 3900x clocks, one of the chiplets is probably from a bin that's slower than a 3600.

Same for MSI B450M Mortar MAX

This on the ASRock forum.

It seems that Asrock is skipping AGESA 1.0.0.3 abba for the 300/400 boards and will integrate the next AGESA instead.

As AMD mentioned, they are going to release another AGESA code in these few week.
Newer AGESA will mainly to solve boost frequency, Matisse compatibility and other issues.
We plan to release newer AGESA which should improve users experience on 300/400 series platform.
Once we received new AGESA, we'll release new BIOS as soon as possible.

Doesn't seem right now with other 400 series boards getting ABBA.

Quite possibly this is more aimed at OEM's who won't need to worry as much (read spend as much) on cooling a 65w TDP CPU vs a 105w TDP CPU.

 

[willhub]

Slightly cooler, better clocks and higher cinebench score.

I like ABBA.

Roman has a new video using 5000Mhz ram with 3900X. Funny enough he says is impressed it worked out of the box by just selecting the XMP profile. While 9900K needs hours of manual tweaking to work.
How far AMD has come in just 2 years!!!

Ofc perf wise not that impressive when we can get over 60000MB/s read with 3800C16

 

[chrcoluk]

Its worth pointing out that the 3700U is NOT Zen 2, it is infect Zen+ and Vega, last generation Ryzen 2000, 12nm.

Why AMD chose to do this to themselves, why they don't use Zen 2 and Navi for their Portables is beyond me...

probably spare chips which would sell better rebranded as 3000 series would be my guess.
